IPC: G11C8/18
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To accurately restrict a word line boosting operation time in a simple circuit configuration by providing a time limit circuit for delaying the start-up of a boosting power source circuit for boosting an potential of a selected word line equally to or more than a power source potential to be behind the rise of a chip selecting signal by a prescribed time. SOLUTION: When the chip selecting signal CE is inputted to the time limit circuit 11 before an internal contact point (a) of a high resistance load memory cell 10 is saturated to an actually using state voltage VCC, an output of a current mirror type sense amplifier constituting the time limit circuit 11 becomes a high potential, and a logic output of an inverter of the time limit circuit 11 becomes low to operate the word line boosting power source circuit 12. However, when the chip selecting signal CE is inputted after the saturation, the circuit 12 does not operate.  Consequently, by constituting this SRAM in order to operate the word line boosting power source circuit only for a period of time when the output of the time limit circuit 11 becomes low at the time of a shift from a data holding mode voltage to the actually using state voltage VCC, the word line boosting operation time can be in a range of 10-25ms.
